Abstract (en)

[origin: WO9525383A1] The invention relates to a process and a device (14) for equalising the voltage distribution to gate-controlled, series-connected semiconductors (2). According to the invention, in the on-conditon, predetermined switch-off delays are called depending on the measured value of a load current (iL) and said delays are updated following switch-off depending on a wrong-voltage distribution found. This provides a process and a device (14) for equalising the voltage distribution to gate-controlled, series-connected semiconductors (2), the regulation being always automatically performed according to the latest operating status.
